Appliances

Why NSI Protection Plus?

Our service plan is an economical way to extend the terms of your product's manufacturer parts & labor warranty.

Most manufacturer's limited warranties leave customers with no protection against the rising cost of repairs.

Even the best products can malfunction and the most minor repairs can cost hundreds.

About NSI Protection Plus

Administered by Warrantech and insured by AmTrust Financial, NSI Protection Plus is the largest service network in the industry with 30 years of building the network and over 22 million in paid claims.

The most comprehensive repair plans in the business!

  • Day one coverage on special features
  • Removal and reinstallation coverage
  • $25 Laundry credit (Washers and Dryers)
  • 5 year appliance contracts include 10 year major component coverage
  • $250 Food credit (per incident, eligible products)
  • The only true "No Lemon Guarantee" in the business
  • No "CAP" on repairs or replacement, unlimited repairs.

Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Reliable Easy to install. Little Pricey...

Matlacha 7/10/2019

I already have a LG 18kBTU in a vacation home on the water on the Gulf but wanted to add a separate unit for the bedroom. This does the job. If it is as reliable as my other one it will last a long time. These units are a little noisy though.

skoro 6/13/2019

Replaced a 35 year old Carrier unit. Much better performance and quieter as well. Love the remote as the old unit had only two settings: on or off. I noticed the electric bill has gone down noticeably too.

Problem solved

JB477 9/5/2018

I live in northern Michigan in an 800 sq. ft. cabin on a small lake. Michigan summers here can be pretty brutal when it comes to heat and humidity and down right uncomfortable. I installed my LG LT1216CER Air conditioner in a new LG AXSVA1 26 In. Wall Sleeve for Through-the-Wall Air Conditioners and I have been comfortable since. The installation was pretty simple and the entire cabin stays cool and dry.

MickLV 7/28/2018

I bought it for my 2-car garage and it is quite effective lowering an extremely hot place at times by 5 to 10 degrees. Plus it does take humidity out of the air. My garage is now a place I can work in on occasions without streaming perspiration.

Superior Cooling Ability

MoSonn 7/26/2018

I live in a small house under 450 square feet. Unit is powerful enough to easily cool living room kitchen bedroom bath and hallways with the setting usually no lower than 74 degrees even on the hottest days. The energy saving feature is wonderful. The unit is however somewhat noisy but that could also be because of the size of my place. My friend who also lives in one of these small houses installed one as well and is equally pleased with the unit. Would highly recommend to anyone looking for an attractive efficient and well-constructed air conditioner.

New unit for an existing through the wall hole

Bakeman 7/25/2018

Unit is running great it is cooling the main living area of a 1500 sq ft ranch home. We are extremely pleased with how close the measurements were in the online specs and the included material to help insulate fill small gaps was a great help to us. The existing hole that we have has existed for decades so trying to find a unit that was close to our existing hole was a big deal. We have had to turn it off on occasion as it gets too cold shows that it is working great so far. Manual/instructions that were included were fair. Some slight improvements would have helped me a bit but nothing that I could not overcome.

So far it is great

Buzz64 7/6/2018

Partitioned off a portion of the garage insulated it and installed work benches. Got this air conditioner to tame the heat. It is 97+ on the other side of garage which is just insulated. After a week of cooling switched to econ mode and it has held a steady 75 degrees. Room is about 12x20x12. I got the LC sleeve and installed both in about 3 hours. Instructions for the sleeve install are not very clear but not hard to just look at the thing and figure it out. Id recommend waiting to permanently install screw-in the sleeve until you test fit the air conditioner to get the right amount of overhang for your trim. Im very happy with the unit so far its been running about a month with outside temps in the 93+ range with 103 heat index.

LG through the wall a/c unit

MS Mudbug 6/15/2018

I purchased this for our apt. It is a through the wall unit as opposed to a window unit. It cools well but the unit is loud regardless of fan speed selected. Even on low it is loud. Also the energy efficient mode which cycles on/off every three minutes will make you want to throw yourself off the balcony. It drives me nuts so I never use it. I understand these units are not quiet but did not expect it to be this loud.

Another LG Champion

Aaf49 6/2/2018

I purchased this A/C to replace a 1987 Panasonic that decided to die after 30 years. So far I am impressed with its ease of installation cooling ability remote operation and multiple functions. It is a little noisy on high fan but that is not a problem for me.

A great cooling unit.

Gummy 5/31/2018

I bought this AC about a month ago to replace an old unit that was 32 years old. I did the install myself and the unit is doing a great job of cooling a room that is 14 x 32. As far as anthing that could be just a little better the front grill viberates just a little when the compressor kicks on but no big deal.

Fantastic Through the Wall A/C unit

AC Through the Wall 5/25/2018

I purchased this unit just a few days ago to replace a very old unit 28yrs old. Its working great VERY quite for this type of appliance. Cools the room VERY quickly and the cooling process cycles on and off extremely quite. The remote feature is very convenient as well the different options of operating are very easy to follow on the LED screen. Well done LG Ill be getting another one for a different room. RD Las Vegas
